I vape at low wattage, 6.5 on all my Kanger Protank style tanks (bottom coils) at 2.0Ω on all my APV's (the ones I can set wattage anyway)
Used these before w/ a tiny strip of rolled up organic cotton for an awesome vape but found they gooped up really fast

Then found these, the silica is much thicker than from the ones above, don't even need to use cotton for wicking, they still wick awesome and just need the coil...

Just rebuild the head, snip off the extra silica, and all the coils I have done have been right at 2.0Ω and vape solid! Saves me about 30-60 seconds each rebuild and when I rebuild 10-20 at a time..that adds up
Just a heads up for those that DIY and rebuild your kanger or bottom coils
